C# 使用C使用crystalreportsviewer打开表单#

我正在处理一个应用程序。在datagridview中，我创建了event

dataGridView1\u CellContentDoubleClick

，它应该打开另一个包含

crystalreportviewer组件的窗体，然后将crystalreportdocument的路径传递给crystalreportviewer并加载该报表，以便它可以显示数据

到目前为止，我已经做到了：

    private void dataGridView1_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
    {
        //string that carries path of the report document
        string path = dataGridView1.SelectedRows[0].Cells["ReportPath"].Value.ToString();

    }

您可以在项目中创建一个新表单。然后，在该表单的代码中，您将构造函数更改为采用作为报告路径的字符串参数

然后用于显示该表单的代码是：

//CrystalReportForm is your new form.
CrystalReportForm form = new CrystalReportForm(path); 
form.Show(); //or form.ShowDialog();

不确定我是否理解您的意思，我有一个需要传递变量（crystal document path）的事件，我需要从中打开另一个表单（显然就是这个部分）Form3 form=new form（）；form.Show（）；但在那张表格3中，我需要加载crystalreportviewer并传递crystalreport文档的路径，以便查看器可以打开报告…据我所知，您已经有了该表格中的crystalreportviewer组件了？所以你唯一需要的就是路径？在这种情况下，请更改Form3的构造函数，使其包含一个字符串参数，您可以使用该参数获取crystal report viewer将加载的路径。是的，表单具有crystalReportViewer1组件：创建表单后，我通过拖放crystalreportviewer组件添加了该组件。。。我已经添加了额外的代码来查看我到目前为止所做的工作……没问题。由于我是初级/中级开发人员，我理解这一点：有时部分代码无法获得足够的信息来理解事情的工作原理，因此我添加了完整的代码，以使其他人更容易理解。干杯
